The bride wore Marchesa!

For her surprise, top-secret wedding to Ryan Reynolds at Boone Hall Plantation in Mount Pleasant, South Carolina over the weekend, Blake Lively could have worn just about any designer she desired.

The fashionista's choice? Marchesa. The Gossip Girl actress, 25, wore a one-of-a-kind couture bridal gown with a hand-draped silk tulle bodice adorned with crystal and rose gold embroidery, according to a release from the fashion house -- founded by Georgina Chapman and Keren Craig, and beloved by many Hollywood stars. (Lively has represented Chanel as the face of its Mademoiselle bag, and also recently signed on to be the face of Gucci's Premiere fragrance.)

Members of the bridal party also wore the brand: custom-made blush silk chiffon gowns with crystal embroidered detail, the release reveals.

Lively and Green Lantern costar Reynolds, 35, began dating about a year ago. The chosen venue -- outside Charleston -- was also the setting for one of the most romantic movies of all time: The Notebook, based on Nicholas Sparks' novel and starring Ryan Gosling (who briefly dated Lively) and Rachel McAdams.
